温度是影响昆虫生长发育的重要生态因子,这是昆虫对环境适应性的一种反映。赤眼蜂也不例外。在大量繁殖利用赤眼蜂时,掌握温度对赤眼蜂生长发育的影响尤其重要。在其他条件相同时,将赤眼蜂置于适温下饲养,则发育快,生活力强,繁殖率高;得知赤眼蜂的发育起点,就能在低于发育起点的温度下贮存蜂种;知道低温或高温对生长发育的不利影响,就可事先采取措施,加温或降温繁蜂;求得有效积温,就可预料在某温度下繁蜂所需要的天数,以便计划繁蜂。在进化适应过程中,对温度的反应的差异
Temperature is an important ecological factor affecting insect growth and development, which is a reflection of the adaptability of insects to the environment. Trichogramma is no exception. In the breeding of Trichogramma multiplication, the temperature control Trichogramma growth and development are particularly important. Trichogramma under the same conditions, the Trichosanthes were placed at the appropriate temperature, the development of fast, strong vitality, high reproductive rate; Trichogramma learned the starting point of development, can be stored below the developmental threshold temperature Species; know low temperature or high temperature on the adverse effects of growth and development, measures can be taken in advance to heat or cool the bee; obtain effective accumulated temperature, can be expected at a certain temperature the number of days required for bumble bees in order to plan bumble bees. Differences in response to temperature during evolutionary adaptation
